FIELD: opencast rock mining. SUBSTANCE: two water-proof hoses are placed in the well, the diameter of one of the hoses corresponds to the well diameter, and the other hose has a smaller diameter, a detonator is attached to this hose. Placed in the hose of the larger diameter is an oxidant, whose integranular space is filled with a concentrated solution of ammonium nitrate; the hose of the smaller diameter accommodates an oxidant, whose intergranular space is filled with the rated quantity of combustible component making up 5.5 to 6.0% of the volume of the deep-hole charge so as to provide a zero oxygen balance. EFFECT: facilitated procedure. 2 cl, 1 dwg
